CORN-PLANTER.

SPECIFICATION formingpart of Letters Patent No. 238,161, dated February22, 1881 Application filed November 23, 1880. (Model.)

, ence being bad to the accompanying drawings,

and to letters or figures of reference marked thereon, which form a partof this specification, in which- Figure l is a top plan of a seed-cupwheel, actuating-slide, and bottom of a corn-planter seed-box. Fig. 2 isa top plan of the parts shown at Fig. 1, except the seed-cup wheel andannular'plate on which it rests. Fig. 3 is a sectional elevation in theline :0 m in Fig. 1.

Fig. 4 is a perspective of the head below the seed-wheel. Fig. 5 is aperspective of the head shown at Fig. 4. with the top plate thereofremoved. Fig. 6 is a perspective of the bottom plate of the head shownat Fig. 4: with partof the hinged lugs in place. Fig. 7 is a sectionalelevation of the parts shown at Fig. 4 in the line 3 y in Fig. 5.

This invention relates to corn -planters of that class in which anintermittent rotary motion in one direction .is given to a seed-cupwheel by lugs or tappets ona reciprocating slide, and in which a fixedplate is located between the slide and seed-wheel; andthe inventionconsists in improvements in constructions and combinations of partshereinafter described, and set forth in the claims hereto annexed.

Referring to the drawings by letters, the

same letter indicating the same part in the different figures,letterArepresents the bottom plate of a corn-planter seed-box, and B theslide, which reciprocates lengthwise thereon, being held in its path bylugs 01. on the bottom plate, and limited in the extent of its throws bylugs b on the slide. The slide B has limbs b b. The bottom A and slide Bare parts of an ordinary planter, except tappets and stops on the slide,hereinafter described.

D is a head formed of a bottom plate, E,

'naled in the plate A.

hinged lugs F, journalplate G, and a top plate, H. The head D isjournaled on a stud-bolt, a, which. projects upward from the bottomplate, A, between the limbs b b, and passes through the plates E and H,so that the head D may rotate thereon, and may be removed therefrom whenrequired. The stud-bolt a. may be attached to the plate E and be jour-The head D may be journaled in various ways to the bottom plate, A. Theplate E has radial grooves e, in which the lugs F are seated, with theirouter ends projecting from the plate E. Each lug F has a transversegroove, f, in its upper side near its inner end, and its lower side andinner end, f, made concentric with the groove f, immediately below thegroove, and has a projecting shoulder, f, as shown at Fig. 7.

A bar, g, semicircular in its cross section, rests with its curved sidein each groove], which, while they hold the lugs in place, also act asjournals on which they (the lugs) may be swung upwardly at their outerends until their shoulders f strike the bottom of plate E and limittheir upward movement. In raising the outward ends of the lugs F theyrock on their rounded bottom portions, f. The bars g are preferablyunited at their ends to form a polygonal ring-like plate, G, as shown atFig. 5, which is held from close contact with the walls of the grooves fby resting on parts e of the plate E. (See Fig. 6.) j The bottom of theplate H rests on shoulders e of the plate E and holds the plate G inplace. Flanges 6' project upward from the periphery of the plate E,exterior to the lower part of the plate 11, and secure the plate H fromlateral displacement, and it is further'held by screwboltsl, which passthrough two of the longer flanges e and into the plate H. Grooves h inthe lower part of the plate H'permit the lugs F to swing upward. Theplate H may be solid, but is preferably cup shaped, as shown at Fig. 4,to reduce its weight, and has projections H from opposite sides of itsupper edge, with a groove, 12/, in theouter ends of each projection.

J is an annular plate held in a fixed position above the slide B by lugsa, which project upward from the bottom A, to which lugs it is bolted.The fixed plate J is common in certain classes of planters, and forms abottom for the seed-cups k, which are arranged in circular series in anannular seed-cup wheel, K, that is located above the fixed plate J. Theplate J has the usual opening j for the discharge of seed from theseedwheel K in the manner common in planters withintermittingly-rotating seed-wheels. The seed-wheel K is connected withthe plate H by lugs which fit the recesses h in the plate H.

L is a lug or tappet projecting upward from the limb b of the slide B,and has an inclined side, 1, and a side, 1, about perpendicular to theslide. A similar tappet, L, is located on the limb I), and has slopingand vertical sides. (Indicated by same letters respectively.) Thetappets L L are not located in a line at right angles with the slide,but are obliquely located with reference to such line, as shown at Figs.1 and 2.

M is a lug or stop projecting upward from near one end of the limb -b,and M is a similarstop projecting upward from the opposite end of thelimb b.

In making a throw of the slide B toward the right hand the tappet L willbe brought in contact with one ofthe lugs F, and, forcing it forward,will givea partial rotation to the seedwheel and head D. When thelast-described throw of the slide is terminated one of the lugs F willcome in contact with the stop M on the slide, and thus arrest the motionof the seed-wheel. In making the partia rotation referred to one of thehinged lugs F was raised by the inclined side of the tappet L and passedover said tappet. The relative positions of the slide B, seed-wheel K,and its attached head D, when the slide has completed a throw toward theright hand, are shown at Figs. 1 and 2. In making a throw in the reversedirection the tappet L acts upon a lug, F, while another lug, F, swingsover the tappet L, and the stop M arrests the motion of the seed-wheel,and thus by alternate throws of the slideforward and rcturnanintermittent motion in one direction is given to and seed discharged inmeasured quantities at the termination of each movement of theseed-wheel K.

I do not claim in this application the hinged lugs on the seedwheel per.90, nor, broadly, in combination with a seed-wheel and reciprocatin gslide, as such features are shown and claimed in another applicationwhich I have filed contemporaneously with this 5 but What I claim asnew, and desire to secure by LettersPatent, is

1. In combination with a seed-cup wheel, slide, and fixed plate locatedbetween the seed-cup wheel and slide, a head connected with and locatedbeneath the seed-cup wheel and provided with swinging lugs,substantially as and for the purpose specified.

2. In combination with a slide and seed-cup wheel, head connected withand located beneath the seed wheel and provided with swii'iging lugs,substantially as and for the purpose specified.

3. In combination with the slide having tappets L L and stops M M, ahead having lugs F hinged thereto and a seed-wheel secured to and aboveit, substantially as and for the purpose specified.

4. 1n combination with a seed-cup wheel, lugs hinged to a head below theseed-wheel and adapted to receive motion from a reciprocating slide,substantially as and'for the purpose specified.

5. The'plate E, having recesses e, in combination with the lugs F,having groovesfand shoulders f, and thejournal-platc G, substantially asand for the purpose specified.

G. The plate E, having recesses c, in combination with the lugs F,having grooves f and shoulders f, thejournal-plate G, and cap H,substantially as and for the purpose described.

7. In combination with a seed-cup wheel, a head located beneath it andprovided with swinging lugs, for the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.
